Data collected at livestock slaughter can be a useful source of non-specific health indicators including clinical signs, symptoms and proxy measures [1]. When monitored in near real-time, this data can enable the detection of both livestock and human health threats [1]. In the United States (US), the Federal Meat Inspection Act requires ante-mortem inspection of animals and post-mortem inspection of carcasses by veterinarians to ensure the meat product will be fit for human consumption [2]. Inspections are carried out by the United States Department of Agriculture (USDA) Food Safety Inspection Service (FSIS) and results are recorded in the Public Health Information System (PHIS), including the reason for condemnation if the animal or carcass is deemed unfit. Since April 2016 the USDA, Animal and Plant Health Inspection Service (APHIS), Veterinary Services (VS) has used data from the PHIS to monitor changes in the weekly count/rate of cattle condemnations for three cattle types, beef cows, dairy cows, and fed cattle (steers and heifers), and for selected condemnation reasons (central nervous system (CNS), dead, emaciation, mastitis, moribund, pneumonia, pyrexia, and septicemia). These eight reasons were chosen from 45 potential reasons recorded at condemnation as likely to identify clinical signs associated with foreign animal diseases of interest and to monitor trends in important animal health issues such as pneumonia and mastitis.

Objective: Use United States cattle slaughter condemnation data as an animal health indicator for early detection of health events and to characterize trends in condemnation reasons.

The recent focus on the 'One Medicine' concept has resulted in an increased awareness that the control of diseases in animal populations, whether zoonotic or not, can be of great public health importance. Zoonotic and foodborne diseases represent an immediate threat to the health of human populations, while rapid spreading diseases in animals can compromise the food-supply and the economy of a country or region. On the other hand, animal populations can serve as sentinels, and continued surveillance can prevent the emergence and/or rapid spread of pathogens potentially harmful to humans. However, awareness of the activities developed in the field of animal health is still low among public health workers. To date, the cooperation between public health and animal health epidemiologists has mainly involved the control of outbreaks of foodborne diseases. Greater cooperation between the two fields, however, could improve prevention and reduce the number of such outbreaks.

Objective

To discuss opportunities to improve the synergy between animal and public health and increase awareness, among public health workers, of the concept of animal health.

Syndromic surveillance of livestock animals at points of concentration, such as livestock markets, has the potential to provide early detection of endemic, zoonotic, transboundary, environmental, and newly emerging animal diseases and to identify animal health trends. In the United States, inspectors at livestock auction markets routinely observe animals for clinical signs of disease, but do not usually document the number of cattle or clinical signs observed. The purpose of this pilot program was to demonstrate the benefit and feasibility of utilizing inspectors at livestock markets to record the total number of animals observed and the number displaying body system-associated clinical signs/syndromes (BSAS). This project is a Federal and State partnership between the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) Veterinary Services (VS) and the Texas Animal Health Commission (TAHC). The livestock market syndromic surveillance pilot project is part of a broader effort in VS to develop and monitor non-traditional animal health surveillance data streams. These data streams include clinical sign information from private veterinary practitioners, veterinary diagnostic laboratory test requests, and livestock slaughter facility condemnations.

Objective

To describe the design and implementation of a syndromic surveillance program in selected cattle markets in Texas, USA.

Protecting U.S. animal populations requires constant monitoring of disease events and conditions which might lead to disease emergence, both domestically and globally. Since 1999, the Center for Emerging issues (CEI has actively monitored global information sources to provide early detection impact assessments and increased awareness of emerging disease events and conditions. The importance of these activities was reinforced after September 11, 2001, and these processes are now part of the U.S. Department of Agriculture’s response to Homeland Security Presidential Directive 9. Electronic information sources available through the Internet have recently changed the way animal health information is gathered, processed and shared. To respond to these changes, CEI developed a dynamic system containing automated and semiautomated components that process information from various sources to identify, track, and evaluate emerging disease situations.

Objective

This paper describes a system of automatic and semiautomatic processes for data gathering, assessment, and event tracking used by the CEI to enhance monitoring of global animal health events and conditions.

Pesticides are used in agriculture and in the home to control pests such as insects, weeds, fungi and rodents. Pesticide poisoning in animals is usually due to misuse or accidental exposure. Information on poisonings in livestock in North America is largely lacking. Examples of hotlines in the U.S. for animal poisoning consultations include the APCC ($65.00 fee) and the Pet Poison Helpline (PPH) ($59.00 fee). The APCC fields calls 24 hours/day, 7 days/week about animal poisonings from the U.S., its territories and Canada. Using data from almost 4 years of APCC calls we describe the occurrence, category and class of pesticides involved, and outcomes of suspected pesticide exposures in livestock. This information is useful to raise awareness, encourage the proper use of pesticides and identify specific pesticides with negative impact on livestock health.

Objective:

This study characterizes the epidemiology of suspected pesticide poisoning in livestock in the United States (U.S.) and Canada using data from calls to the American Society for the Prevention of Cruelty to Animals (ASPCA) Animal Poison Control Center (APCC).

The Johns Hopkins University Applied Physics Laboratory is collaborating with epidemiologists of the US Dept. of Agriculture's Animal and Plant Health Inspection Service (APHIS) Center for Epidemiology and Animal Health (CEAH) to increase animal health surveillance capacity. CEAH monitors selected syndromic animal health indicators for stakeholder reporting. This project’s goal was to extend this capacity to bovine veterinary laboratory test accession data.

Objective:

Standardize selection of indicator data streams and corresponding alerting algorithms for syndromic, reportable disease, and confirmed diagnostic categories derived from veterinary laboratory test order data for bovines.
